Exploring Energy-Efficient Housing

This week in seminar, we focused on energy codes and passive housing standards for buildings. The Passive House Standard is an energy efficient building approach that creates comfortable, healthy, and environmentally friendly spaces while using up to 90% less heating energy than conventional construction. Originally developed in Darmstadt, this standard has gained significant traction in the United States.

As part of this topic, we met with Jonathan Arnold, a developer who specializes in energy-efficient mixed-use projects. We were able to tour his energy-efficient apartment buildings at 2nd and Delaware. He guided us through the development process and explained how passive housing principles were applied to make the project both efficient and unique.

One of the key features of the building is its defensible courtyard space, which provides a sense of safety for residents while also encouraging social interaction. The project is also transit oriented, located near the Kansas City Streetcar and the Riverfront Heritage Trail, promoting walkability and healthier lifestyles.

The building envelope plays a major role in its performance. It uses extremely thick, airtight windows and construction techniques that prevent air leakage, maintaining indoor temperature efficiently. The L-shaped buildings are supported by six structural columns, allowing flexibility in floor plans for future adaptations. Additionally, the use of rockwool insulation enhances soundproofing, creating an interior environment that feels quiet and controlled similar to a recording studio.

During the tour, we were able to experience the building firsthand. The layout felt open and accessible, and the upper levels offered impressive views looking north toward the Missouri River and south toward downtown Kansas City. This visit gave us valuable insight into how passive housing is being implemented locally and how it can influence future development in Kansas City.

Following the tour, we regrouped in class to reflect on what we learned and began selecting topics for our upcoming assignment, “The Role of Designers in Housing Access.”
